Water is a common chemical substance that is essential for the survival of all known forms

of life. In typical usage, water refers only to its liquid form or state, but the substance also has a

solid state, ice, and a gaseous state, water vapor or steam; it is one of the very few substances

to be found naturally in all three states on earth. Water takes many different forms on Earth:

water vapor and clouds in the sky; seawater and rarely icebergs in the ocean; glaciers and

rivers in the mountains; and the liquid in aquifers in the ground.

Water covers 71% of the Earth's surface. On Earth, it is found mostly in oceans and other large

water bodies, with 1.6% of water below ground in aquifers and 0.001% in the air as vapor,

clouds (formed of solid and liquid water particles suspended in air), and precipitation.

Saltwater oceans hold 97% of surface water, glaciers and polar ice caps 2.4%, and other land

surface water such as rivers, lakes and ponds 0.6%. A very small amount of the Earth's water is

contained within biological bodies and manufactured products. Other water is trapped in ice

caps, glaciers, aquifers, or in lakes, sometimes providing fresh water for life on land.

Water moves continually through a cycle of evaporation or transpiration

(evapotranspiration), precipitation, and runoff, usually reaching the sea.

Clean, fresh drinking water is essential to human and other life. Access to safe drinking water

has improved steadily and substantially over the last decades in almost every part of the

world. However, some observers have estimated that by 2025 more than half of the world

population will be facing water-based vulnerability, a situation which has been called a water

crisis by the United Nations. Water plays an important role in the world economy, as it functions

as a solvent for a wide variety of chemical substances and facilitates industrial cooling and

transportation. Approximately 70 percent of fresh water is consumed by agriculture.

e)the amount of rain, snow, etc. that falls in an area

f)a permanent covering of ice, esp around the North and

South Poles

g)the process by which water is converted from its liquid

form to its vapor form and thus transferred from land and

water masses to the atmosphere

h)the process where water contained in liquid form in

plants is converted to vapor and released to the

atmosphere

i) a liquid, that can dissolve another substance

j)extremely important and necessary
